First of all my Motor/Clutch and Tranny are not installed (no weight on subframe). I first installed the Drivers side Upper and Lower control arm and connected my Spindle. I then let all the tension off the coil spring and noticed that I had forgotten the upper control arm bumper. The way everything sits at the moment there is no way to get that bumper in. Question is do I need to pull things apart now and install it, or will the be room once I put some weight on the subframe (will there be room)??
